Captair® Flex™, by Erlab®

Erlab®, a worldwide leader in non ducted fume hoods, introduces captair® Flex™, a new generation of non ducted mobile filtration fume hood. Based on a new modular design, the captair® Flex™ range ensures optimal operator protection by being able to adapt itself to the handling of liquid and solid toxic chemicals, separated or combined, in laboratories and clean rooms.

Based on the Flex™ technology, a new modular filtration column, a single unit can be configured to the protection needs of laboratories. This has been rendered possible with the combination of molecular and particulate filtration. The filtration column air tightness is ensured by using a gel sealing technology applied on the whole perimeter of the filtering cartridges.

This technological breakthrough allows the user to doing a very large variety of liquid handlings such as dilutions, titrations, extractions, transfers, solid handlings such as sieving, grindings, weighings, formulations, compressions, to combinate liquids and solids for dissolutions, filtration and extraction. This new line can also be adapted to the lab environment such as cleanrooms up to class ISO 5 classification.

The large range offered by captair® Flex™ allows answering to lab space requirements and retention capacities needs. The SD line offers 1 column with enclosures from 80 cm to 160 cm wide while the XL line can be equipped with 1 to 4 filtration columns, from 100 cm to 180 cm wide. From routine handlings to big evaporation or instruments caging up, captair® Flex™ offers a real protective solution to the whole lab needs.

The compliance of the captair® Flex™ range with the 2009 AFNOR NF X 15-211, the major standard related to ductless filtering fume hoods insures users real performance criteria with regards to: Filtration efficiency (the emission concentration at the filter exhaust must be lower than 1% of the handled product TLV), Containment (the maximal concentration of of SF6 tracer gas at the measuring points as described in the standard
procedure is 0.1 ppm) and the air face velocity (the air face velocity at any point of the front openings must be between 0.4 and 0.6 m/s).

According to these standard requirements, Erlab® has published a new Chemical Listing, a booklet containing an exhaustive list of chemicals that can be handled into the filtering fume hood. This new version demonstrates the technical performance and the knowhow developed by Erlab®.

Filtration technologies used in the design of captair® Flex™ non ducted filtration fume hoods enable to protect laboratory users but also to protect the environment: Since no ductwork is required, it totally eliminates the direct discharge of pollutants into the atmosphere, reduce carbon footprint as it does not generate any pollution linked to energy production unlike a traditional ducted fume hood. Its installation is quick and
easy.

There is no need for a ductwork linked to an air supply / air extraction system, in comparison to traditional ducted systems. Its setting up can be realised at any time, without any complex forward planning. Users can also benefit from the use of an immediately available unit, easy to relocate without disturbing room air balance.

Lastly, captair® Flex™ answers to one of the major objective of our modern world: the energy savings.

The ductwork air balance, essential to the proper operation of a traditional ducted fume hood however is also the source of very important energy consumption. Captair® Flex™ filtered enclosures do not generate any energy costs associated with the use of expensive extraction systems or conditioned air supplies. Operational costs can, by consequence, remain at a minimum even when taking into account filter changes.
